Looked at a 2009 Jayco 1206 today and was unable to get the overhead lights to work. Plugging in the accessory fan/light wouldnt work either. PUP was plugged in and outside light and water pump worked. I didnt have anything to plug into an outlet but the ground fault outlet by the sink lit up and could be tested. I checked the fuse box and all the fuses were fine and breakers were on. I turned the fridge on AC but couldnt tell if it on. I did not hear the compressor kick on. The PUP has sat in storage for 2 years and the battery was not hooked up. I used the electrical issues to negotiate a lower price and put down a deposit. ANY IDEAS WHAT IS WRONG? Is this an easy fix?
